Sandvik Coromant 5754888 TPMR432 2025 Turning Insert

Product Description

The SANDVIK COROMANT 5754888 is a solid carbide turning insert in the TPMR432 2025 grade, designed for precision metal-turning operations on CNC lathes and turning centers. The insert features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which provides wear resistance and thermal protection during continuous and interrupted cuts. The 60-degree triangle geometry (insert shape code T) offers three usable cutting edges. With a 0.5-inch inscribed circle and a corner radius of 0.03125 inches (1/32 inch), this insert is suited for finishing and semi-finishing passes. Primary target workpiece material is stainless steel (ISO material code M).

This insert is part of the SANDVIK COROMANT T-Max S series and is intended for use in compatible T-Max S toolholders accepting TPMR-style inserts with a clamp-holding method. Typical applications include turning stainless steel components in job shops, aerospace, and general machining environments. The neutral hand orientation allows use in standard right-hand and some left-hand toolholder configurations. The ISO designation for this insert is TPMR 22 04 08 2025, and the chip breaker designation is 53. This insert is sold individually; the minimum order quantity is 10 units.

Installation Notes

This insert is installed and replaced by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before changing inserts. Use the correct clamping screw and torque procedure specified by the toolholder manufacturer for TPMR-style pockets. Inspect the insert pocket and clamp for wear or debris before seating the new insert to ensure proper contact and secure retention.
